One advantage of inbreeding is getting rid of lethal recessives, but at some point a good outcross will invigorate the strain. <BR/> My family is long-lived, and has many first cousin marriages going back to many generations on Martha's Vineyard.Marielhttps://www.blogger.com/profile/13754507453707351095noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-78164064585818094432009-03-16T22:56:00.000+02:002009-03-16T22:56:00.000+02:00Is it possible that inbreeding favors longevity be...Is it possible that inbreeding favors longevity because the offspring are less likely to inherit genetic material from one parent that conflicts with that of the other?Average Joehttps://www.blogger.com/profile/12203996329459638052noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-50778627391219721752009-03-14T21:41:00.000+02:002009-03-14T21:41:00.000+02:00I doubt that inbreeding favors longevity at all (w...<I>I doubt that inbreeding favors longevity at all (why would it?)</I><BR/><BR/>There is clear evolutionary pressure for longevity in humans due to the increasing reliance on and cost of learning.

Since mutations tend to be loss-of-function at the transcription level, it may be that the most advanced features of longevity are showing up in recessives.Jim Boweryhttps://www.blogger.com/profile/12686155123469135528noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-62024215968738634552009-03-14T20:51:00.000+02:002009-03-14T20:51:00.000+02:00Perhaps inbreeding is indirectly indicating the li...Perhaps inbreeding is indirectly indicating the likelihood that a given person has lived his life in favorable circumstances.

Personally I doubt that inbreeding favors longevity at all (why would it?) and therefore it's likely that this study is more realistic than the others: it just reads the data properly. <BR/><BR/>Are quasi-centenarians a problem? Maybe. But what does the data for average old people of c. 70-85 y.o. (which is the life expectancy in developed countries for males and females respectively)? People in their 70s are not "survivors" but average old people, they should clarify the issue.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.com
